Porsche 911 Turbo S: In the works?

Street word has it that a Porsche 911 Turbo S might be in the works.

According to Team Speed, a new 997.5 Turbo S is coming, and coming soon. When? Spring 2010. And how much power? Pure speculation, but 540 to 550 hp sounds about right. And figure on standard ceramic brakes, RS-style center lock wheels, and some sort of unique bodywork (more strakes?) to differentiate it from mere mortal Turbos.
